My sentiments exactly. Ridiculous! …and I mean that in the best possible
way ;)

Like the {3,7}, the vertex-turning version will be a great deal
more tractable. I configured the two easiest possible vertex-turning
600-cells (by using your 120-cell and 600-cell puzzle data). One has only
trivial tips and one has cells sliced like gelatinbrain’s 5.1.1. I’ll put
them at the bottom of this email in case any would like to try them out.

Whereas the face-turning puzzle is borderline unusable on my computer,
these are both nice and smooth, and the pieces per cell not nearly as
scary. Of course, the number of cells still is! However, it might be
possible to solve the trivial tips version in a few hours, maybe even less
(120 tips at one tip per minute = 2 hours).

A large face-shrink and smaller sticker-shrink allows you to see the
stickers for a tip compacted together, which felt like it might be a good
way to approach a solve. Something like this

It doesn’t work so well in practice though because you can’t click pieces
towards the center (trying that always selects pieces from intervening
faces). I guess sticker-click twisting would be required to make these
particular display settings usable.

Cheers,
Roice

P.S. I agree with Melinda that it would be nice to be able to turn off the
cell borders sometimes.
